According to Luke, Jesus was once asked by a scholar how he (the scholar) was to inherit eternal life.
Jesus answers by asking him what is written in the law.
The scholar answers, "You shall love the Lord your God with all your heart, with all your soul, with all your strength, with all your mind, and your neighbor as yourself."
Jesus indicated that the man had answered correctly. But the man pressed on and asked Jesus, "So, who is my neighbor?"
Jesus responds with what is arguably his most famous parable of the Good Samaritan.
In the parable, Jesus tells about a man who was beaten on the road, robbed and left for dead. A priest and a Levite (a member of the tribe tasked with taking care of the Temple and other religious functions) passed the man by without rendering any assistance. A Samaritan came by and helped the man, took him to someone that could care for him and paid to ensure that care was given.
Now, there were some cultural undercurrents in the story that need to be mentioned. The priest and the Levite were afraid that by rendering assistance, they would be made impure/unclean and thus unable to be the holy and devout Jews that they were.
Due to the existence of a large degree of enmity between Jews and Samaritans, the Samaritan was logically the one least likely to lend assistance. Jesus created a situation in which the one person who was probably not a physical neighbor was in-fact the only one acting the way a neighbor should act.
Jesus then asked his questioner, "Who do you think was the one that acted most like a neighbor to the beaten man?"
And what does that make all the Christians who would deny their products and services, pizza, wedding cakes, or whatever, to people who happen to be gay?
Do these people actually read their bibles?
Christians who would deny their goods and services to LGBT peoples are very similar to the priest and the Levite in the story. All of them believe themselves to be holy, righteous and pure and that somehow, by helping a beaten man or baking cake for two men who love each other, they will somehow ...
For the life of me, I can't figure out how they get the notion that by baking a cake they are somehow being harmed, or that if they are required to do so, that they are somehow promoting homosexuality and that their religious liberties are being infringed upon. I don't know of any major religion that officially endorses outright discrimination of this type. Christ, to the contrary, specifically directs us to treat others as neighbors with dignity and respect, regardless of who or what they are.
Do they somehow think that by refusing to bake the cake that the two men will suddenly say to each other, "Golly, if he won't bake the cake, we're obviously wrong to love each other. Let's go find somebody with a uterus. Thanks for setting us straight baker."
Or maybe they feel that by baking a cake someone else is going to see that cake and think, "Wow, it sure would be great to have a beautiful cake with two women figurines holding hands on it at my wedding. I'm going to tell my penised fiancée that the engagement is off."
But those are actually unlikely, because those thoughts would result from true (albeit misguided) concern for the wellbeing of others. No, what they are really thinking is that somehow by baking a cake for a gay loving couple that someday they will find themselves making love to someone of the same sex and that God almighty will condemn them to hell for it.
How are we to gain eternal life, again?
